Subject: [PATCH v7] dt-bindings: mtd: spi-nor: add optional interrupts
 property

Some spi flash memories have an interrupt signal which can be used for
signalling on-chip events such as busy status or ecc errors to the host.

Add binding for "interrupts" property so that boards wiring this signal
may describe the connection.
